Tewkesbury is a market town and civil parish in the north of Gloucestershire, England. The town grew following the construction of Tewkesbury Abbey in the twelfth century and played a significant role in the Wars of the Roses. It stands at the confluence of the River Severn and the River Avon, and became an important trading point. The town gives its name to the Borough of Tewkesbury. The town lies near the border with Worcestershire, marked largely by the Carrant Brook.
Ordnance Survey places 111 postcodes in Tewkesbury in the Environment Agency's rivers-and-sea flood-risk dataset (Risk of Flooding from Rivers and Sea). Each postcode is counted once, under the worst band any of its properties reaches; together they hold 1,083 properties in the EA dataset's likelihood bands.
| EA likelihood band | Postcodes (worst band) | Properties in the EA dataset | of which homes |
|---|---|---|---|
| High | 44 | 239 | 192 |
| Medium | 14 | 74 | 52 |
| Low | 52 | 761 | 623 |
| Very low | 1 | 9 | 3 |
| All bands | 111 | 1,083 | 870 |
This dataset covers flooding from rivers and the sea only — one of five flood sources. Surface water, groundwater, sewers and reservoirs are assessed separately, so a postcode missing from it is not proof that a place cannot flood. The band describes the land around properties (allowing for defences), not any single address and not today's conditions.
…and 11 more at-risk postcodes, listed on the district pages below.

Two mapped watercourses are about the same distance from the middle of Tewkesbury's gauges: the River Avon (about 30 m) and Mill Avon (about 50 m), so this page cannot say which one is nearer to you.
Distances along the river are from the point on each watercourse nearest the middle of Tewkesbury's gauges. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
